Abstract: A stabilized chewing gum product containing an L-aspartic acid derived sweetener in its free form and method for manufacture thereof are disclosed. The chewing gum product includes at least two portions, one of which includes, in its free form, Aspartame (APM) as an artificial, low calorie sweetener. Also included in the APM-containing portion can be an organic acid which will maintain the pH of the portion at a level conducive to maintaining the stability of APM. A second portion can include flavoring agents, and optionally, at least one moisture-containing agent. The portions are arranged in surface-to-surface relationship whereby contact between the APM and the flavorings and/or moisture-containing agent of the second portion is substantially reduced. The stability of APM and, consequently, of the chewing gum product is substantially increased.

Abstract: Bei einem Verfahren zur Herstellung von hochtemperaturbeständigen Folien aus Polyimid-Polymerisaten wird eine Lösung des Polymerisates in einem organischen Lösungsmittel durch eine Schlitzdüse (3) einer Filmbildungseinrichtung ausfließen und in einem das organische Lösungsmittel enthaltenden wässerigen Fällbad (4) koagulieren gelassen und die aus koaguliertem Film bestehende Folie (6) abgezogen, das organische Lösungsmittel entfernt und die Folie (6) getrocknet. Um ohne nachfolgende Orientierung ausreichende Festigkeitseigenschaften zu erreichen und damit auch bessere Formbeständigkeit bei erhöhten Temperaturen zu erzielen, wird der in der Schlitzdüse (3) gebildete Film über einen kurzen Luftspalt (5) direkt in das wässerige Fällbad (4) abgezogen, einer anschließenden Wärmebehandlung unterworfen, um einen durchsichtigen homogenen Film zu erhalten, das organische Lösungsmittel sodann durch Behandlung mit einem wässerigen Extraktionsmittel entfernt und die Folie (10) schließlich getrocknet.

Abstract: The invention relates to a wire-forming apparatus, namely a winding and bending machine for leg springs. …<??>The prior art is formed by apparatuses having a plurality of tools for bending wire, which is fed in a straight line, the bending tools surrounding the wire path, and by spring-winding machines having a rotatable mandrel for winding up the wire, the wire ends of the spring being shaped by means of bending tools. …<??>The disadvantage of these apparatuses is their structural complexity and limitation to the production of particular spring shapes. A different spring thus requires different tools. …<??>The object of the invention is therefore to reduce the expenditure required for the production of the apparatus and to generalise the shaping operations which can be carried out with the same tools. …<??>The solution to this object is the arrangement of a plurality of tools (86, 88, 90, 92 or 142; 162, 190, 192) on one tool holder (74; 160), which is secured on the free end of a longitudinally displaceable shaft (12) similar to the known mandrel and can be exchanged. By rotational and longitudinal positioning of the shaft by means of its drive, known from the mandrel but controlled in a different manner, each tool present can be moved into the path of the wire and hence brought into use. …<??>The advantage of this solution is the simplification of the structure of the apparatus and the possibility of producing different spring shapes by means of the same tools. …<IMAGE>…

Abstract: An interlocking system for a railway comprises a plurality of processors (A, B and C), the system having an input (1) for receiving input information and an output (2) for providing control information. Each of the processors is adapted to test itself to check that it is operating correctly and each of the processors is also adapted to test another of the processors to check that the other processor is operating correctly, each of the processors also being so tested by another of the processors. The system is shut down or put into a more restricted mode of operation if a fault in its operation is detected, either as a result of a processor's self-testing routine or as a result of one of the processors detecting that another processor is not operating correctly. This achieves the integrity of a "dual-channel" system with only a single "channel" of hardware.

Abstract: A wound dressing comprises a vapor permeable plastic film (10) coated on one side with an adhesive (12) about the periphery of a wound contacting window (14) in the central portion of the dressing. A pair of release liners (16, 18) covers the adhesive coating and include (16', 18') tabs so that the release liners can be peeled from the adhesive coating. Means are provided adjacent to and at opposite lateral sides of the wound contacting window to change abruptly the resistance to peeling of the release liners from the adhesive coated film. Accordingly, when the user feels this change in resistance, he or she knows that the wound contacting window and a small portion of the adhesive about the periphery thereof is uncovered which allows the dressing to be anchored about the patient's wound with the release liners partially in place and the wound contacting window exposed. This minimizes the tendency of the film to wrinkle and/or to fold on itself such that the adhesive adheres to itself.

Abstract: A full-duplex digital speakerphone 10 includes a transmit signal path having an output coupled to a telephone trunk and a receive signal path having an input coupled to the telephone trunk and an output coupled to a loudspeaker means. The speakerphone further includes a room echo cancellation adaptive filter 56 and a trunk echo cancellation adaptive filter 66. Serially coupled within the transmit signal path is a selective suppression block 50 for suppressing a component of a Mu-Law or an A-Law quantization error signal. A second selective suppression block 52 is serially coupled within the receive signal path. Suppression of non-linearities due to Mu-Law or A-Law signal conversion is also accommodated by providing a non-linear signal processing block 40 at an input to an adaptive filter and an optional non-linear signal processing block at an output of the adaptive filter. Each of the blocks emulates and compensates for signal converter non-linearity. The speakerphone facilitates adaptive filter coefficient initialization by beginning a call in a half-duplex mode and switching to full-duplex when filter coefficients are adapted. The speakerphone also has a variable adaptation step size which is a function of a short-term estimate of signal power within the associated transmit or receive signal paths.

Abstract: In a test of the electro-acoustic transmission properties, the telephone apparatus is connected to an evaluation device and a sound transmitter is used which emits acoustic signals for the speaker of the handset. In order to carry out a test which is reproducible and also copes with different types of handsets, it is proposed to arrange a sound transmitter in a test shell which, with its shell opening, bounds the sound inlet of the speaker of a handset in an acoustically sealed manner so that a pressure chamber is produced between the speaker and the sound transmitter. A reference microphone is arranged inside the pressure chamber and identifies, at every frequency of the test signal, a deviation of the operating variables from a predetermined recommended value and reports this to the evaluation device. The evaluation device subsequently supplies, in terms of frequency, a control variable, which compensates the respective deviation, for the operation of the sound transmitter. <IMAGE>
